How do i make specific players spawn with specific weapons?

i have some guns thats for my friends but i dont know how to make only them spawn with the guns, the only way i can do right now is using admin

This isn't a request site but whatever.

local Whitelist = {"",""} -- People that will spawn with weapons.
local Weapons = {game.ServerStorage["Glock 19"],game.ServerStorage["Glock 21"]} -- Put the location of the guns here.
game.Players.PlayerAdded:Connect(function(Player)
	for i,v in pairs(Whitelist) do
		if v == Player.Name then
			for i,v in pairs(Weapons) do
				local A = v:Clone()
				A.Parent = Player.Backpack
			end	
		else
		end
	end
	local C = workspace:WaitForChild(Player.Name)
	if C.ClassName == "Model" then return true end
	C.Humanoid.Died:Connect(function()
		Player:LoadCharacter()
		wait(.5)
		for i,v in pairs(Whitelist) do
			if v == Player.Name then
				for i,v in pairs(Weapons) do
					local A = v:Clone()
					A.Parent = Player.Backpack
				end	
			else
			end
		end
	end)
end)

so idk where to insert the script is it serverscript stuff or where
